Day 2 Fire Weather Outlook

0126 PM CDT Tue Aug 13 2024

Valid 141200Z - 151200Z

An isolated dry thunderstorm risk area has been introduced for
portions of far northern CA into OR. Latest guidance has come into
better agreement regarding thunderstorm potential associated with an
approaching trough. Thunderstorm chances should increase late
afternoon into the overnight/early-morning hours across this region.
Forecast soundings have also trended towards drier mid-level
conditions with PWAT values between 0.6 to 0.8 inches. Given
antecedent dry fuels, dry thunderstorms will be a fire concern.

...Synopsis...
A mid-level shortwave trough is expected to approach the
northwestern California coast on D2/Wednesday, with much of the
Western U.S. characterized by weak, zonal mid-level flow. This
trough could bring some forcing for thunderstorm development
overnight into Thursday morning across northern California into
southern Oregon, but PWAT values > 0.8 and Most Unstable parcel
originating at temps colder than 0C leave some uncertainty on where
dry thunder highlights might be needed.

Surface winds are forecast to remain well below Critical highlight
criteria across the western U.S., though some locally Elevated
fire-weather conditions are possible across portions of southern
Nevada, northwest Arizona, and southern Utah. These conditions will
be confined to local topography, and fuels across much of the
southern Great Basin are not receptive enough to wildfire spread
(due to recent wetting rainfall) to warrant highlights at this time.
